您必须使用 BroadcastReceiver 通过 AlarmManager 安排事件。扩展 BroadcastReceiver 并覆盖 onReceive() 方法，然后您的设备将在完成该方法所需的时间内唤醒。这将让您发送短信或启动服务。

class MyReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(final Context context, final Intent intent) {
        //YOUR CODE HERE
    }
}

请注意，保持设备处于活动状态的唤醒锁只会持续整个 onReceive 方法，因此如果您启动服务或活动，他们可能不会在设备重新进入睡眠状态之前执行所有代码。

在这种情况下，pendingIntent 必须使用“getBroadcast”而不是“getService”来创建。
